Inflatable and expandable slide and pool construction

ABSTRACT

The invention comprises an inflatable and expandable slide and pool construction that permits the user to selectively change the structure of the slide by expanding it to include a pool or basin at the end of the slide. The pool portion may be releasably attached to the front of the slide and may include inflatable sides and an inflatable end bumper. If the slide is a continuous airflow inflatable, the sides of the pool portion may be inflated by the air blower when the sides are released from their attachment to the end of the slide.

CROSS-REFERENCE TO RELATED APPLICATIONS

This claims priority to U.S. provisional application Ser. No. 60/720,340 filed on Sep. 23, 2005, which is hereby incorporated by reference in its entirety into this application.

BACKGROUND OF THE INVENTION

Inflatable slides are an increasingly popular backyard or poolside recreational toy. The slide may be inflated either by filling the slide structure with air via an inflation valve and then closing the valve, or by a continuous airflow from an air blower. In the latter case, as is known, the outer material of the slide body is permeable and allows air to escape at a rate that will maintain the body in an inflated state as air is blown into the body. The slides typically include a ladder or other means to permit the user to climb to the top of the slide, and often include a device for spraying water onto the slide to facilitate sliding. However, known constructions for inflatable slides are fixed in the sense that they do not permit the user to selectively change the slide structure.

SUMMARY OF THE INVENTION

The instant invention permits the user of an inflatable slide to selectively change the structure of the slide by expanding it to include a pool or basin at the end of the slide. The pool portion may be releasably attached to the front end of the slide and may include inflatable sides and an inflatable end bumper. If the slide is a continuous airflow inflatable, the sides of the pool portion may be inflated by the air blower when the sides are released from their attachment to the end of the slide.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 depicts an expandable inflatable slide construction 10 in accordance with the instant invention. In this particular embodiment two slide surfaces 14 are separated by a barrier 16 formed in the slide, but the slide may have a single sliding surface, or several, as desired. Sleeve 12 extends from side 18 of the slide to receive air from an air blower (not shown) to maintain the slide in an inflated state. Ties 13 permit the sleeve to be secured to the blower. For small slides, the slide may be constructed of impermeable material and inflated in the manner of a balloon—i.e., in conventional fashion, using a shut-off valve to close off the inflated body. For larger slides, however, it is recommended that the slide be made of air permeable material and that a continuous air blower be employed to keep the slide inflated, as in known in the field.

A U-shaped end bumper 20 is detachably secured to the front wall 24 of the slide, and provides cushioning when a person slides down the slide and reaches the bottom. End bumper 20 is preferably comprised of an inflatable bladder made of, for example, PVC, that may be sealed off by a valve (not shown); in other words, it is not a continuous airflow inflatable structure. The bladder is enclosed in a cover made of the same material as the sides of the slide, both for continuity of appearance and for protection of the bladder from puncture.

For decorative purposes, members 26 may be formed on each side of the slide and are inflated by the air blower as part of slide construction 10. Extendable legs 36, which will form the sides of the pool, as explained more fully below, are seen in collapsed condition; the legs 36 are secured to the slide front wall 24 and the distal portions 25 of end bumper 20 (FIGS. 2 and 3). The collapsed legs 36 are held in place between end bumper 20 and slide front wall 24 as explained more fully below. Pool bottom 35 (FIG. 4), which comprises a sheet of plastic material such as PVC, is also held in collapsed position adjacent slide front wall 24 (not shown here).

As seen in FIGS. 2 and 3, end bumper 20 may be released from attachment to the slide by unfastening outside fasteners 30 and inside fasteners 32. These fasteners may comprise conventional hook-and-loop materials, straps and buckles, or other devices, as desired. The end bumper 20 may then be pulled away from the front wall 24 of the slide as shown in FIG. 4, thereby extending out pool bottom 35 and pool legs 36. Handles 22 formed in end bumper 20 may facilitate the re-positioning of the end bumper 20.

In FIG. 5, end bumper 20 is seen in its outwardmost position with extendable legs 36 inflated and pool or basin 34 fully formed at the bottom of the slide

FIGS. 6-8 depict the procedure for effecting inflation of the extendable pool legs 36. After end bumper 20 has been pulled substantially to its outermost position, external flap 40 on each leg may be opened via fasteners 42, here shown as zippers. The user may then reach inside and open internal flaps 44, located at each of the ends 24 of the slide, via fasteners 46, again shown as zippers. Air from the air blower may now flow out of the ends of the slide and into the extendable pool legs 36 to inflate them. The user then closes the external flaps 40 to prevent air from escaping from legs 36.

The slide portion of the instant invention may be made from 420 denier polyester or 490 denier Nylon, with a PVC coating, and may be fabricated by well known die-cutting, sonic welding and/or sewing operations. Preferably, the sliding surfaces themselves have an external coating of PVC, while the remainder of the slide and the extendable legs has an internal PVC coating. The air blower unit may be a commercially available 380 watt or 580 watt, 110 volt blower. 

1. An inflatable and expandable slide comprising a slide portion having a front wall at the bottom of the slide, a bumper member, a pair of extendable leg members each having a first and second end, the first ends being affixed to the bumper member and the second ends being releasably attached to the front wall of the slide portion, and a collapsible pool floor member attached to the leg members, the bumper member, and the front wall of the slide portion, whereby upon release of the leg members from attachment to the front wall of the slide portion, the leg members and the collapsible pool floor member may be extended away from the slide portion to form a pool or basin bounded by the leg members, the bumper member, and the lower end of the slide portion.
 2. The slide of claim 1, wherein the leg members are inflatable.
 3. The slide of claim 2, wherein the bumper member is inflatable.
 4. The slide of claim 3, wherein the slide portion is constructed of air permeable material and further comprises a port for receipt of a continuous flow of air from an air blower to maintain the slide portion in inflated condition.
 5. The slide of claim 4, wherein each leg member includes an opening adjacent the front wall of the slide portion through which opening air may enter the leg member from the slide portion so that the leg member may be inflated by the air blower when the leg member is released from attachment to the slide portion.
 6. The slide of claim 5, wherein the front wall of the slide portion includes a pair of flaps corresponding with the openings in the leg members, which flaps may be opened to allow air to flow from the slide portion into the leg members to inflate the leg members.
 7. The slide of claim 6, wherein each of the leg members includes a flap near the end adjacent the front wall of the slide portion, which flap may be opened to allow access to the flaps in the front wall of the slide portion.
